Minus K Technology's
Negative-Stiffness Vibration Isolators Selected for James
Webb Space Telescope Ground Testing
Inglewood, Calif. - Minus K Technology Inc. has been selected
by ITT Space Systems LLC, subcontractor to Northrop Grumman
Corp., to provide vibration isolators for the ground testing
of the new James Webb Space Telescope (JWST) at the Johnson
Space Center (JSC). The JWST will be placed in a vacuum
chamber at the Johnson Space Center and supported by a set
of custom Minus K vibration isolators.
The James Webb Space Telescope is a large aperture infrared
space telescope currently planned to be launched in 2014
from Kourou, French Guiana aboard an Ariane 5 launch vehicle.
JWST is designated to succeed the Hubble Space Telescope
"A major factor in selecting Minus K is our ability
to not only isolate vibrations vertically, but also horizontally
at less than 1 Hz," states Dr. David Platus, president
and principal inventor of the patented negative-stiffness
vibration-isolation technology. "Minus K's passive
isolators do not require air and offer better isolation
performance than air and active isolation systems."
Minus K Technology works with many aerospace and education
laboratories for custom vibration isolation systems. The
company also offers a line of standard bench top and table
vibration isolation products.
